Flux-core welding is the correct answer because it is an arc welding process that utilizes a wire that is fed automatically at a constant speed as an electrode. In flux-core welding, the wire electrode has a core filled with flux material, which creates a shielding gas to protect the weld pool from atmospheric contaminants. This process is commonly used for welding thick materials in outdoor or windy conditions where gas shielding may be difficult to maintain.

The other options are incorrect:

- Stick welding (Option B) uses a flux-coated consumable electrode that provides shielding gas and forms the weld joint.

- TIG welding (Option C) uses a non-consumable tungsten electrode with a separate filler material added to the weld joint.

- Wire welding (Option D) is a broad term that can refer to various welding processes that involve using a wire electrode, but it does not specifically indicate the use of flux-core wire as in the correct option, flux-core welding.
